POWDER-PACKAGE.

Specification of Letters Patent.

Patented Oct. 22, 1918.

Application filed June 27, mile. serial No. 242,254.

To all whom it may concern:

Be it known that I, EMIL FRANK, a citizen of the United States, andresiding at Cincinnati, in the county of Hamilton and State of Ohio,have invented a new and useful Improvement in Powder-Packages, of whichthe following specification is a full disclosure.

My invention relates to a powder package of cardboard or the like, madefrom a single blank, adapted to be folded into a triangular package ofabout one inch or less in thickness, of substantially bellowslikestructure, having a nozzle projection to be punctured.

The invention constitutes an improvement over the device disclosed in mycopending application, Serial No. 197,608, filed Oct. 20, 1917, sincepatented as Patent No. 1,27 6,- 204, dated August 20, 1918, the objectof the present invention being to improve the structure of the packagein binding, cheapen the cost and render the same more efficient.

The features of the invention are more fully set forth in thedescription of the accompanying drawings, forming a part of thisspecification, in which Figure 1 is a plan view of the blank.

Fig. 2 is a plan view of one of the margin bindings.

Fig. 3 is an end view of the age.

Fig. 4 is a top plan view of the package, showing the bindings of Fig. 2applied to the marginal edges of the package.

The blank, Fig. 1, is a substantially dia mond-shaped cardboard formedwith the medial transverse scored line 2, enabling the right and lefthand wings to be folded upon one another in triangular formation. Thepackage is given cubic dimensions by folding marginal sides of thesections 12, 13, 14, 15, defined by scored lines 3, 4, 5, 6, and by twobase sections 16, 17, on opposite sides of line 2 defined by foldinglines 7, 8, parallel with lines 2. The ends 9, 10, of the side pieces11, 11, are cut off straight to squarely abut when the blank is folded;and to constitute the nozzle 40, see Fig. 4, the converging scored lines3, 4, and 5, 6, terminate at their intersection in outwardly extendingscored lines 41, which provide folding lines for the margins 12, 13, 14,15, at the nozzle end of the structure and when formed packfolded formthe nozzle aperture at the lines 9,10.

The blank at the terminal ends of the transverse scored lines 2, 7, 8,is provided with the notches 18, 19. When the blank is folded on scoredlines 2, 7, 8, and the mar ginal sections 12, 13, 14, 15, are bent in atan angle, the edges of the triangular pieces register and form abox-like structure compressible cross sectionally, the flexibility ofthe scored lines providing the bellows-like flexibility.

To secure the folded blank into package structure to seal the packageand to effect this cheaply without impairing this bellows flexibility, Ibind the marginal edges of the several sections with the binding strip35, Fig. 2, preferably of adhesive paper, and of the shape indicated,having an oflset end 36 adapted to be rolled into an approximate cone tocover the apexes of the package. One of these strips is applied to eachof the edges so that each corner is sealed and reinforced by the conicalportion 36 which caps the corner while the medial line of the strip 35coincides with the marginal joint edge of the package.

he strip cap 36 folds over and seals the aperture of the nozzle and isto be punctured when the package is to be utilized as a powder ejector.

Having described my invention, I claim 1. A compressible owder shippingpackage and gun of so stantially triangular shape, having flat top andbottom walls, angled sidewalls converging to a medial joint projectedbeyond the top and bottom, one of the corners bein adapted to constitutea nozzle, and binding strips of paper securing the meeting edges of theside Walls and having oflset ends conically rolled to cap the cornersfor sealing the package and reinforcing the corners without impairingflexibility. I

2. A compressible carton for powder having flat top and bottom walls andoutwardly angnlarly extended side walls, the meeting side edges andcorners being sealed by adhesive paper strips having offset ends wrappedaround the corners.

3. A one-piece cardboard diamond-shaped blank for a powder shippingpackage and gun, of cardboard, substantially diamondshaped, said blankbeing scored diagonally and marginally to allow folding of one triangleSQCLlOH on another, the marginal scored lines providing outwardlyengularly extended sides converging to a medial oint, two of theopposite diagonal corners .of the blank being squarely out off, anddivisionally scored to provide anozzle aperture when the blank is foldedand secured.

l. A polygonal-shaped powder package and gun, having fiat top and bottomand atngnlni-ly extended sides meeting to constitute e medial flexiblejoint one of the Copies 0:: this patent a nozzle, the medial joint rolld around the corner.

in Witness whereof, I hereunto subscribe ny nmne, as attested by the twosubscribing 'vitnessesi EMIL FRANK.
